Description

2 months ago

During picture caching, a minimal dirty region is calculated and supplied to child pictures during the primitive traversal.

However, if those child pictures create an off-screen surface, then they may clip to tightly to the dirty rects, such that a parent blur filter doesn't have enough surrounding pixels to create the correct result.

To fix this, when a blur filter is encountered, it should push a new dirty region that is inflated by the blur radius in this filter.
